That additional two years could mean a bachelor’s degree where you are, plus a master’s degree at one of the schools that you want to transfer to.
I will admit that I do not know high finance at all, and I do not know how a bachelor’s degree from Columbia would be compared to a bachelor’s somewhere else plus a master’s degree at Columbia.
Also, since I do not know finance, I do not know how an MBA would be compared with a master’s in something else such as mathematics or a related field. I would expect that admissions to a top MBA program would be very competitive, particularly for someone without work experience.
